Look at this graph. Just look at it. The colored section represents all color visible to the human eye. The large black triangle shows the Adobe RGB color space, which is the space used by pro apps to process images, and can be captured by some cameras.

And the little white triangle, sat in the middle cutting out a fraction of the available colors? That’s the standard sRGB color space, which is what you’re looking at now on your Mac or iPad or iPhone (but probably not on the Retina iPad mini).

That’s because monitors don’t usually display so many colors. But the Eizo ColorEdge CG247 not only displays the full gamut of Adobe RGB, it calibrates itself too.
